Thigh Flashcards
Which vessels form the smaller sephalic vein and where does it drain?
dorsal vein of little toe and dorsal venous arch, drains into popliteal vein
Which vessels form the greater cephalic vein, and where does it drain?
dorsal venous arch and dorsal vein of great toe, drains into femoral vein.
What are the borders of the femoral triangle
Sartorius laterally and adductor longus medially, apex formed where medial border of satorius meets AL. inguinal ligament forms base superiorly. Floor formed by iliopsoas and pectineus more medially
What are the contents of the femoral triangle?
laterally to medial, Femoral nerve and branches, femoral artery and profunda femoris artery, and femoral vein and profunda femoris vein
What are the boundaries of the adductor canal?
anterolaterally vastus medialis
posteriorly- adductor longus
medially- satorius
What is the function of the adductor canal?
allows passage of femoral artery, vein, sephanous nerve and nerve to vastus medialis from femoral triangle anteriorly to adductor hiatus and popliteal fossa posteriorly.
What is the adductor hiatus?
An opening between the adductor/ hamstring parts of adductor magnus at the end of the adductor canal
What are the attachments of sartorius?
ASIS, sup part of notch inferior to ASIS,
superior part of medial surface of tibia
What is the nerve supply of sartorius?
femoral nerve (L2,3)
What is the function of sartorius?
Flexes/ abducts/ laterally rotates thigh at hip, flexes leg at knee
What are the attachments of pectineus?
superior ramus of pubis
pectineal line, inferior to lesser trochanter
What is the nerve supply of pectineus?
Femoral nerve (L2,3)
What is the function of pectineus?
Adducts, medially rotates and flexes thigh
What are the attachments of iliopsoas?
Illiacus- iliac crest/ iliac fossa/ ala, Psoas maj- Sides otf T12-L5 vertebrae and transverse processes.
Attach to lesser trochanter of femur
What is the action of iliopsoas?
flex thigh at hip, stabilise hip
Name the 4 quadriceps
Rectus femoris
Vastus lateralis
Vastus Medialis
Vastus Intermedius
What is the function of the quadriceps?
RF steadies hip and flexes thigh, all quadriceps extend leg at the knee
What is the innervation of the quadriceps?
femoral nerve (L2-4)
What are the attachments of rectus femoris?
ant inf iliac spine, ilium superior to acetabulum.
Quadriceps tendon to the patella and tibial tuberosity
What are the attachments of Vastus lateralis?
Greater trochanter and lateral lip of linea aspera,
Quadriceps tendon to the patella and tibial tuberosity, lateral patellar retinacula
What are the attachments of vastus medialis?
intertrochanteric line and medial lip of linea aspera,
Quadriceps tendon to the patella and tibial tuberosity, medial patellar retinacula
What are the attachments of vastus intermedius?
Anterior and lateral shaft of femur
Quadriceps tendon to the patella and tibial tuberosity
What are the functions of the muscles in the medial compartment of the thigh?
adduction of thigh,
stabilising trunk when stood on both feet,
correcting lateral sway of trunk,
flexion of extended thigh and extension of flexed thigh
What are the attachments of Adductor longus?
Body of pubis inferior to pubic crest,
Middle third of linea aspera
What is the nerve supply of adductor longus?
Obturator nerve (L2-4)
What are the attachments of Adductor Brevis?
body/ inferior ramus of pubis
pectineal line and proximal part of linea aspera
What is the nerve supply of adductor Brevis?
Obturator nerve (L2-4)
What are the attachments of the adductor part of adductor magnus?
inf ramus of pubis and ischium,
gluteal tuberosity, linea aspera, medial supracondylar line
What is the nerve supply to the adductor part of adductor magnus?
Obturator nerve (L2-4)
What are the attachments of gracilis?
Body and inferior ramus of pubis,
superior part of medial surface of tibia
What is the nerve supply to gracilis?
Obturator nerve (L2,3)
What are the attachments of Obturator externus?
Margins of obturator foramen, obturator membrane,
trochanteric fossa of femur
